Absolutely essential on our ski trip. I love that. There was so many in this box so my family was able to just grab a couple on their way out the door. Below 20 temperature is these proved to be very useful. They held the heat temperature for so long and super easy to activate with just a couple of little shakes and letting some air hit them. I mean, we could use these pretty much the entire day.

Great. Give it a little while to activate then the heat is good and warm that lasts well over 12 hours.

These handwarmers are perfect for keeping me comfortable during infusions. I’m at the infusion centre for 6 hours and even with the heated chair and heated blankets my hands end up ice cold and I can’t feel them. These handwarmers are fast, don’t require any power, aren’t messy, no smell, they stay warm more than 12 hours and can be held or dropped in an insulated bag to create a super warm pocket to keep my hands toasty. I bought a 10 pack to start, and after using those up I was eager to reorder. They are single use.

Amazon's star rating system designates 5 stars = I love it, 4 stars = I like it. The Super Warmers deserve five stars for delivering on their promise, but I find them excessively hot. If I had to use them in extreme conditions, I might feel differently. The price paid for the quantity offered is a bargain, but the less potent regular hand warmers might be a better value for some people. Bigger and hotter is not going to be as useful in many circumstances.These warmers are, indeed, SUPER, warmers. They are roughly twice the size of the typical individual “hand size”, but they pack more than twice the punch.Everyone’s field conditions are going to be different so there isn’t going to be a one-size-fits-all review anywhere here. The best I can do is contrast these with the smaller hand warmers and how I typically use those.I typically use the smaller hand warmers at the foot of a sleeping bag. On 30 to 50 degree nights in a tent, one small hand warmer (not these Super Warmers) usually does the job of keeping my feet warm. I would not dream of substituting the larger, super warmer in that application. The labeling even says to not use them when you sleep. There is also a warning about not using them if you are arthritic unless you consult a doctor (see attached photo for more warnings).I haven’t tried it, but the amount of heat the super warmer produces would suggest that it could serve as a “space heater” in a single or two man backpacking tent configured with a fly, especially if you had a small battery powered fan to circulate the air. I know this sounds ridiculous—backpacking, space heater, fan—all oxymoronic terms. I’m only trying to give you a sense of the energy that is packed into one of these Super Warmers.Just as the temperature rating of sleeping bags seldom seem to be accurate (conditions vary—the bag’s isolation from the ground, ground temp., tent use, wind, clothing worn, body fat, etc.) the amount of use you get from the Super Warmer is going to depend on many variables. I’ve never been ice-fishing, but if there is any circumstance where they might be especially appreciated, that would seem to be one. Or a hunter waiting in a blind for hours, unable to move around.Also note that the images Amazon has supplied with the product description show BOTH the Super Warmer and the smaller hand warmers that come two to a packet. The graphics might help you see their relative size in the palm of a hand.Final recommendations: Try to get a couple of these locally before you commit to a larger order. Anyone who is driving in severe winter weather conditions should have a supply of these in their safety kit.

I use these in my outdoor cat houses and they keep the bedding warm for the cats and they last long too!

I bought these HotHands body and hand super warmers for my husband to use during the cold weather. He works outside as a technician, and these kept him warm all day, literally! Even after work, they were still warming his hands. He was so impressed, he shared a few with his friends, and now they’re buying them too. I’m so glad I found these and I will definitely be ordering more. Highly recommend for anyone spending long hours on the cold.
